Hola a todos!!!!
Necesito que alguien me ayude a comprimir un directorio con varios archivos dentro, y luego me de la posibilidad de descargarmelo donde yo quiera, he estado mirando por internet y he encontrado una libreria llamada ZipArchive.lib.php que me permite hacer lo que yo quiero pero el problema es que la carpeta que necesitaria comprimir y descargar es mayor al que me deja esa libreria y no se como modificarla.
os adjunto la libreria ZipArchive vale?
